Google does restrict traffic to search

While surfing today through my college network, I was greeted by a webpage which I hadn’t seen over all my years using Google It stated that “Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot.” and in order to continue you will have to fill the Captcha.

 

Now thats a surprise given the fact any College network would be having too many simultaneous connections that would be on google.com. Well filling in the Captcha made life easier and Google did not ask me the captcha again.

Here is the Official Support Thread for the Issue
